The guy that is doing the testing on the new Condor 9mm barrel (one of the reasons I just bought the airgun) told me the barrels (Wolthar of course) will be released in a few months. They are testing different pellets and a round ball as well but the 77 grain Eun Jin is getting about 150 fpe at 930 fps. They also tested a 58 grain Eun Jin.
